Volcanos

Roundup of Global Volcanic Activity

Stromboli (Eolian Islands, Italy): According to the local mountain guides and visitors, explosive activity at Stromboli is currently at elevated levels. Several vents in the crater terrace produce strong and frequent strombolian explosions. Access to the summit area is frequently closed, but for those visiting the island at the moment, good viewpoints are also found along the Sciara del Fuoco up to 400 m elevation (permitted limit).

Etna (Sicily, Italy): Decreasing tremor and weakening thermal signals suggest that the explosive / effusive activity from the vents at the eastern foot of the NE crater still continues, but at reduced rate. At least one lava flow seems to be still active.

Sakurajima (Kyushu, Japan): Activity has been unusually low at the volcano since about 2 weeks. The first explosion during August occurred this morning, producing a plume that rose less than 1 km above the summit.

Fuego (Guatemala): An increase in activity with more frequent and stronger explosions took place yesterday, but the volcano has again been calmer today. The volcano observatory reported that explosions with ash plumes of up to 800 m height occurred at rates of 3-4 per hour and produced a plume drifting for about 12 km W and NW. Ash fell on the villages of Morelia, Santa Sophia and Yepocapa. The explosions were accompanied by moderate booms and shock waves that let roofs and windows of houses in a radius of 6 km vibrate.

Ubinas (Peru): Activity remains low. A few small ash explosions occurred today, with plumes rising a few 100 m above the crater.
